His contributions on the paleontology in Colombia has been mainly on the descriptions of ammonites and Etayo has helped describing many fossiliferous geologic formations of Colombia. Etayo obtained his MSc. degree in geology and geophysics from the Universidad Nacional de Colombia in 1963, and his PhD in paleontology from the University of California, Berkeley in 1975. Biography In 1962, Etayo Serna published his first work about the species '' Codakia orbicularis'' and '' Codakia orbiculata''. He has defined many geologic formations of Colombia in the 1960s and 1970s. Etayo, together with fellow paleontologist María Páramo, collaborated in describing the first dinosaur fossil found in Colombia, '' Padillasaurus'' from the Paja Formation, close to Villa de Leyva, Boyacá.Carballido et al., 2015 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization. Spanish is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

Etayoa
''Etayoa'' is an ungulate of the family Carodniidae in the order Xenungulata that lived during the Early Eocene (~ 55 Ma) in northern South America. Etymology The genus of the type species ''Etayoa bacatensis'' was named by palaeontologist Carlos Villarroel after Fernando Etayo Serna, who contributed extensively to the paleontology and stratigraphy research in Colombia. The species epithet ''bacatensis'' refers to Bacatá,Villarroel, 1987 the name in Muysccubun for the main settlement of the southern Muisca Confederation; the name of which has been used for the current Colombian capital Bogotá, founded in a different location than the original Bacatá. Description The type species fossil specimen consists of a partial mandible with teeth, found in the Bogotá Formation in the locality Ciudad Bolívar of Bogotá, Colombia.1987 Description of ''Etayoa bacatensis''- Paleobiology Database The estimated size of the ungulate is the size of a dog. 2011 Un xenungulado del Paleoc ...

Ungulate
Ungulates ( ) are members of the diverse clade Ungulata which primarily consists of large mammals with hooves. These include odd-toed ungulates such as horses, rhinoceroses, and tapirs; and even-toed ungulates such as cattle, pigs, giraffes, camels, sheep, deer, and hippopotamuses. Cetaceans such as whales, dolphins, and porpoises are also classified as even-toed ungulates, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. The term means, roughly, "being hoofed" or "hoofed animal". As a descriptive term, "ungulate" normally excludes cetaceans as they do not possess most of the typical morphological characteristics of other ungulates, but recent discoveries indicate that they were also descended from early artiodactyls. Ungulates are typically herbivorous and many employ specialized gut bacteria to allow them to digest cellulose. Some modern species, such as pigs, are omnivorous, ...

WorldCat
WorldCat is a union catalog that itemizes the collections of tens of thousands of institutions (mostly libraries), in many countries, that are current or past members of the OCLC global cooperative. It is operated by OCLC, Inc. Many of the OCLC member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. The database includes other information sources in addition to member library collections. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services (such as resource sharing and collection management). WorldCat is used by librarians for cataloging and research and by the general public. , WorldCat contained over 540 million bibliographic records in 483 languages, representing over 3 billion physical and digital library assets, and the WorldCat persons dataset (Data mining, mined from WorldCat) included over 100 million people.

Stenorhynchosaurus
''Stenorhynchosaurus'' is an extinct genus of pliosaurid plesiosaurs which lived in the Early Cretaceous of South America. The type species and only known is ''Stenorhynchosaurus munozi''. It was a medium-sized pliosaur, reaching an adult body length of . Discovery and naming Fossils from the front of a snout of a plesiosaur were discovered in 2000 on the property of Jorge Muñoz, in Loma La Cabrera, near Villa de Leyva in Boyacá, Colombia, on grounds of marine origin dating from the Late Barremian epoch of the Cretaceous. Muñoz reported the find to the local authorities, who in turn gave notice to staff of the Museo Geológico José Royo y Gómez administered by the Servicio Geológico Colombiano in Bogotá. Then was made the excavation of the nearly complete skeleton between 2004 and 2005, in collaboration with the Fundación Colombiana de Geobiología ("Colombian Geobiology Foundation"), and the remains being then transferred to Bogotá, assigning the catalog number VL ...

Boyacá Department
Boyacá () is one of the thirty-two departments of Colombia, and the remnant of Boyacá State, one of the original nine states of the "United States of Colombia". Boyacá is centrally located within Colombia, almost entirely within the mountains of the Eastern Cordillera to the border with Venezuela, although the western end of the department extends to the Magdalena River at the town of Puerto Boyacá. Boyacá borders to the north with the Department of Santander, to the northeast with the Bolivarian Republic of Venezuela and Norte de Santander, to the east with the departments of Arauca and Casanare. To the south, Boyacá borders the department of Cundinamarca and to the west with the Department of Antioquia covering a total area of . The capital of Boyacá is the city of Tunja. Boyacá is known as "The Land of Freedom" because this region was the scene of a series of battles which led to Colombia's independence from Spain. The first one took place on 25 July 1819 in ...

Villa De Leyva
Villa de Leyva, also called Villa de Leiva, is a touristic colonial town and municipality, in the Ricaurte Province, part of the Boyacá Department of Colombia. The town is a Colombian National Heritage Town and is on the tentative list for UNESCO World Heritage Sites. Villa de Leyva is located west of the departmental capital Tunja. It is about three hours by car or bus from Bogotá. Located away from major trade routes in a high altitude valley of semi-desert terrain, and with no mineral deposits nearby to exploit, the town has undergone little development in the last 400 years. As a consequence, it is one of the few towns in Colombia to have preserved much of its original colonial style and architecture: the streets and large central plaza are still paved with cobblestones, and many buildings date from the sixteenth century. This has resulted in Villa de Leyva becoming one of Colombia's principal tourist attractions, and it was declared a National Monument on December 17, 19 ...
